GEORGES. PAGE, OF STANLEY, NEW- JERSEY.

SUBSTANCE OR PRODUCT FOR CARPET-LININGS, 80c.

SPECIFICATION forming part of Letters Patent No. 237,770, dated February 15, 1881,

Application filed March 24, 1880.

To all whom it may concern Be it known that I, GEORGE SHEPARD PAGE, of Stanley, township of Ohatham, Morris county, New Jersey, have invented a new and improved substance or product consisting of a combination for the manufacture of an improved felting material similar in appearance and made in a similar manner to roofingfelt, sheathing, and carpet-lining, of which the following is a specification.

This invention relates to that class of materials used for carpet-lining, sheathing, &c.; and it consists in the combination of certain waste products, hereinafter mentioned, to produce a fabric or felt specially adapted for that purpose.

' The materials of which this carpet-lining may be composed are tan-bark, usually spent, or tan used and exhausted in the tanning of leather, hairthat is, the hair of animals usually the short hair removed by mechanical processes in the treatment of hair, and which is not generally available for manufacturing purposes, and the raw paper-stock, known in the trade as colors or satinets, orthewaste of carpet and woolen mills, known as shoddy, and low-meadow hay or straw. I may, however, use sawdust, ground cork, ground sponge, ground shavings,or the ground seed,pods, and stalks of the wild flag, commonly called cato -nine tails, or any equivalent material, in place of the tan, or mixed with it.

In the manufacture of carpet-linin g, sheathing, or other similar materials, as a new substance or product, from the several materials above specified, I grind the tan, cork, sponge, shavings, Wild flag, or sawdust in the ordinary beating-en gine, or in any machine for triturating this material in a way similar to that in which paper-stock is prepared, until the same is brought to the degree of fineness or pulverization requisite for its manufacture into paper felt, which degree will be readily ascertained by any one acquainted with the manufacture of paper felting. I preferto use from fifty to sixty per cent. of tan, sawdust, or shavings in manufacture, though I do not limit myself to this proportion. The colors or satinet rags or similar materials are added in the proportion offivc (5) to ten (10) per cent.,not1im- (No model.)

itin g myself, however, to this proportion. The hay, cork, sponge, shavings, wild flag, or other similar material is added in the proportion of five(5) to ten (10) per cent. of each,not limiting myself, however, to this proportion. These are ground or beaten in the usual way in which paper-stock is prepared. Before drawing the pulp from the rag-engines from fifteen (15) to twenty-five (25) per cent. of animal hair is added. I may, however, add the animal hair to the pulp contained in the stuff-chest or in the vat just preceding its being taken up to be formed into paper or felt. These proportions that I have given will vary with the requirements of the manufactured stock.

If greater strength is required, I add more of the colors, the hair, and of the hay to the tan, cork, sponge, shavings, flag, or sawdust used. I prefer tan to sawdust, as being a more elastic material.

It is sometimes desirable to color this new product in any desirable shade by the use of any of the ordinary coloring materials, or to saturate or treat the same with coal-tar or any asphaltic or bituminous substance or composition.

I may omit the use of one or more of these materials, except the tan, substituting a larger proportion of some of the other materials specified or supplying some equivalent material.

The advantages of my invention are, adding to the useful arts a new and cheap product. As used in this connection, the price of the ordinary materials, such as rags, having risen so high, being used for the finer paper, and even for cloth, it is extremely difficult to find suitable stock for the coarse papers, even at any reasonable market price. It also provides a more elastic substance, better suited for carpet-lining than hitherto known. This product is also less liable to the ravages of moth, and is therefore a better protection to carpets.

The object of my invention is to provide a single ply or layer, having greater advantages, at a reduced price, than have hitherto been known.

The prepared product is ordinarily made up into rolls, as carpet-lining, sheathing, and roofing-felt are made up. It may, however, be made and sold in sheets of any suitable size.

It may also be made into double or treble papers; but I prefer to make it and market it as a single ply.

Having thus described my invention, What 5 I claim, and desire to secure by Letters Patent, is

As a new article of manufacture, a felt or fabric composed of spent tau, cork, sponge,

shavings, sawdust, animal hair, rags, hay, and the stalk and seeds of Wild flag, when treated to and combined in the manner substantially as described, and for the purposes set forth.
